Oscar James Dunn: A Case Study In Race & Politics In Reconstruction Louisiana, Brian Mitchell

LSU New Orleans Theses and Dissertations

The study of African American Reconstruction leadership has presented a variety of unique challenges for modern historians who struggle to piece together the lives of men, who prior to the Civil War, had little political identity. The scant amounts of primary source data in regard to these leaders’ lives before the war, the destruction of many documents in regard to their leadership following the Reconstruction Era, and the treatment of these figures by historians prior to the Revisionist movement have left this body of extremely important political figures largely unexplored. This dissertation will examine the life of one of Louisiana’s …

The study also examined the differences between these educators’ willingness, preparedness, and selected demographic and descriptive characteristics, which included teacher education, educational setting, and support provided for inclusion. As such, it contributed to both the theory and the practice of teaching students with disabilities in inclusive settings.

The sample included willing general and special education teachers in one suburban school district in the southeastern United States. The instrument was a modified version of …

Data Exploration Interface For Digital Forensics, Varun Dontula

LSU New Orleans Theses and Dissertations

The fast capacity growth of cheap storage devices presents an ever-growing problem of scale for digital forensic investigations. One aspect of scale problem in the forensic process is the need for new approaches to visually presenting and analyzing large amounts of data. Current generation of tools universally employ three basic GUI components—trees, tables, and viewers—to present all relevant information. This approach is not scalable as increasing the size of the input data leads to a proportional increase in the amount of data presented to the analyst.

We present an alternative approach, which leverages data visualization techniques to provide a more …

Habitat Characteristics Affecting Site Occupation In Wintering Henslow’S Sparrows At Mississippi Sandhill Crane National Wildlife Refuge, Mary E. Nicholson

LSU New Orleans Theses and Dissertations

Henslow’s sparrow (Ammodramus henslowii) winters in recently burned sites in pine savannas of the Southeastern United States. Previous studies have suggested that factors such as seed abundance and litter depth are important to wintering Henslow’s sparrows. My study asked how habitat variables including vegetation structure, seed abundance, and arthropod abundance predict Henslow’s sparrow site occupancy at Mississippi Sandhill Crane National Wildlife Refuge. In this study, Henslow’s sparrow more often occupied sites burned one growing season earlier than sites burned two growing seasons earlier, and did not occupy sites burned three or more growing seasons earlier. Data indicated that mass …

A Study Of Organizational Structures Impacting Noncredit Workforce Education And Their Effects On Determining Workforce Development Strategies In Louisiana's Community And Technical Colleges, William S. Wainwright

LSU New Orleans Theses and Dissertations

The Lumina Foundation (2007) indicates that 54 million adults in the workforce are seeking noncredit education opportunities in a credit course/program delivery system designed to meet the needs of traditional college students. Working adults seeking continuing education coupled with dislocated workers as a result of changing economic situations represents this growing population. Community and technical colleges in Louisiana benefit from a for-credit formula funding model and do not benefit from a formula funding mechanism that supports noncredit education enrollments. As Louisiana’s community and technical colleges face continuous budget challenges resulting from economic recession, college leaders are making critical decisions in …

Play Therapists’ Practice Patterns And Perceptions Of The Factors That Influence Caregiver Engagement In Play Therapy, Adrianne R. Lolan

LSU New Orleans Theses and Dissertations

Much effort has been expended to increase the awareness and understanding of play therapy among consumers and practitioners (Landreth, 1991) since its introduction by Virginia Axline during the 1940s. As with any form of counseling, Leblanc and Ritchie (1999) have noted there are factors considered key to successful play therapy treatment outcomes. Play therapy research shows a positive relationship between parent's involvement in play therapy and successful outcomes (LeBlanc & Ritchie, 1999; Bratton, Ray, Rhine, & Jones, 2005) but little research exists to document specific practice patterns and perceptions of play therapists in relation to achieving caregiver engagement. The purpose …

Statistical Spectral Parameter Estimation Of Acoustic Signals With Applications To Byzantine Music, Kyriakos Michael Tsiappoutas

LSU New Orleans Theses and Dissertations

Digitized acoustical signals of Byzantine music performed by Iakovos Nafpliotis are used to extract the fundamental frequency of each note of the diatonic scale. These empirical results are then contrasted to the theoretical suggestions and previous empirical findings. Several parametric and non-parametric spectral parameter estimation methods are implemented. These include: (1) Phase vocoder method, (2) McAulay-Quatieri method, (3) Levinson-Durbin algorithm,(4) YIN, (5) Quinn & Fernandes Estimator, (6) Pisarenko Frequency Estimator, (7) MUltiple SIgnal Characterization (MUSIC) algorithm, (8) Periodogram method, (9) Quinn & Fernandes Filtered Periodogram, (10) Rife & Vincent Estimator, and (11) the Fourier transform. Algorithm performance was very precise. …

An Experimental Study Of Formation Of Circulation Patterns In Laminar Unsteady Driven Cavity Flows Using Particle Image Velocimeter (Piv) Techniques, Jon Farkas

LSU New Orleans Theses and Dissertations

Abstract

An experimental study is conducted to determine the velocity fields, from development to steady state, in a square enclosure due to movement of a constant velocity lid using Particle Image Velocitmetry (PIV). Experiments were conducted with water, seeded with hollow glass sphere particles 10 microns in diameter, at three different lid velocities leading to Reynolds numbers in the high laminar to transitional range. Driven Cavity Flow is a classic fluid dynamics case often used for benchmarking of computational codes. Previous work has primarily focused on improving computational codes, experimental work is lacking and focused on obtaining steady state readings. …

Measuring Early Numeracy Of Kindergarten Students In A Group Setting, Stacy A. Winck

LSU New Orleans Theses and Dissertations

Early identification practices in assessment are crucial to preventing academic failure as well as identifying students at-risk for later learning disabilities. The PAM Early Numeracy Screening is a set of subscales designed to measure early numeracy in kindergarten students in a group setting. Given that the existing early numeracy measures are individually administered, the purpose of the current study was to explore the psychometric properties of the PAM Early Numeracy Screening. Correlational analysis was the primary research design used to investigate the evidence of reliability, criterion-related validity, and construct validity of the PAM Early Numeracy Screening.

Multivariate Models And Algorithms For Systems Biology, Lipi Rani Acharya

LSU New Orleans Theses and Dissertations

Rapid advances in high-throughput data acquisition technologies, such as microarraysand next-generation sequencing, have enabled the scientists to interrogate the expression levels of tens of thousands of genes simultaneously. However, challenges remain in developingeffective computational methods for analyzing data generated from such platforms. In thisdissertation, we address some of these challenges. We divide our work into two parts. Inthe first part, we present a suite of multivariate approaches for a reliable discovery of geneclusters, often interpreted as pathway components, from molecular profiling data with replicated measurements. We translate our goal into learning an optimal correlation structure from replicated complete and incomplete …

A Dynamical Study Of The Evolution Of Pressure Waves Propagating Through A Semi-Infinite Region Of Homogeneous Gas Combustion Subject To A Time-Harmonic Signal At The Boundary, John Eslick

LSU New Orleans Theses and Dissertations

In this dissertation, the evolution of a pressure wave driven by a harmonic signal on the boundary during gas combustion is studied. The problem is modeled by a nonlinear, hyperbolic partial differential equation. Steady-state behavior is investigated using the perturbation method to ensure that enough time has passed for any transient effects to have dissipated. The zeroth, first and second-order perturbation solutions are obtained and their moduli are plotted against frequency. It is seen that the first and second-order corrections have unique maxima that shift to the right as the frequency decreases and to the left as the frequency increases. …

Development Of A Novel Electron-Transfer Secondary Reaction Matrix, Characterization Of The Site–Specificity Of Novel Bilin-Lyase, And Fundulus Grandis Protein Expression Investigation Using Mass Spectrometry, Mohamed N. Boutaghou

LSU New Orleans Theses and Dissertations

Reported in this dissertation are the results of investigations performed at the New Orleans Center for Mass Spectrometry at the University of New Orleans. The projects that are detailed in the coming pages take on a variety of subjects, but a common thread is that each employs matrix-assisted laser desorption/ionization (MALDI) mass spectrometry to solve a problem. Fundamental aspects of MALDI in-plume ionization are implicated in the introduction of a newly developed electron-transfer secondary ionization matrix. The remaining projects are related to the ever expanding field of proteomics. Mass spectrometry was used to investigate the site specificity of a newly …

Therapist's Perceptions Of Walk And Talk Therapy: A Grounded Study, Bridget L. Mckinney

LSU New Orleans Theses and Dissertations

Our society has become less physically active (U.S. Department of Health and Human Services, 2010) and less connected to nature than ever before (Berger & Mcleod, 2006). Spending leisure time indoors, technological advancements, urban living, and car dependent communities have led to these changes (Dustin, Bricker, & Schwab, 2010; Hansen-Ketchum, Marck, & Reutter, 2009; Norman & Mills, 2004). As a result, physical health and mental health is deteriorating (Dustin et al., 2010; Maller, Townsend, Pryor, Brown & Leger, 2005). Physical activity and nature can each produce mental and physical health benefits; some approaches such as adventure-based counseling and wilderness therapy …

Horizontal Violence In The Nursing Work Environment: Beyond Oppressed Group Behavior, Therese M. Mendez

LSU New Orleans Theses and Dissertations

The United States has been experiencing a nursing shortage since the mid-1990s. The shortage is expected to deepen as the provisions of the 2010 Patient Protection and Affordable Care Act are enacted. Horizontal violence is a negative phenomenon in the nursing workplace that contributes to difficulty in recruiting and retaining nurses in hospitals. Horizontal violence has been described as a form of mistreatment, spoken or unspoken, that is threatening, humiliating, disrespectful or accusatory towards a peer. The effects of this nurse on nurse aggression can be devastating for the nurse involved and also for the patients under the nurse's care. …

Self-Assemblies Driven By The Hydrophobic Effect, Haiying Gan

LSU New Orleans Theses and Dissertations

Water is a simple molecule but is an essential part of life. One key aspect of the properties of water is the hydrophobic effect, and whilst there is an appreciation of this phenomenon at the macro-scale (raindrops falling off leaves) and the micro-scale (the structure of cellular systems), a complete understanding at the molecular level still eludes science. Addressing this issue, our studies involve synthetic supramolecular compounds that assemble in water via the hydrophobic effect.

First of all, a novel water-soluble deep-cavity cavitand was synthesized. It possesses four endo methyl groups on top rim of the cavitand, eight water-solubilizing carboxylic …

Exchange Flows In An Urban Water Body: Bayou St. John Responses To The Removal Of Flood Control Structures, Future Water Elevation Control, And Water Quality, Robin L. Schroeder

LSU New Orleans Theses and Dissertations

Bayou St. John, an urban water body extending south from Lake Pontchartrain, has two anthropogenic structures that regulate flow from the Lake . The City of New Orleans has plans to remove the inner control structure to improve water quality. Field and numerical methods used in this study show removing this structure increased water elevations throughout the Bayou but resulted in lower water elevation signal amplitudes that caused a lower tidal flow exchange from north to south. Bulk Richardson numbers showed mixing was inversely related to flow and the Bayou generally remains stratified. Resuspension of contaminated sediment could negatively impact …

Synthesis And Biological Evaluation Of Aeruginosin Based Compounds And Self-Assembly Of Glucosamine Based Compounds, Navneet Goyal

LSU New Orleans Theses and Dissertations

Aeruginosins are a family of marine natural products containing mostly non-proteogenic amino acids. These compounds contain a common 2-carboxy-6-hydroxy-octaindole (Choi) rigid bicyclic structure. Many aeruginosins are inhibitors for enzymes involved in the blood coagulation cascade, such as thrombin and Factor VIIa. In order to understand the structure activity relationship (SAR) of the aeruginosins and to discover novel anticoagulants with potentially improved inhibitory and pharmacokinetic properties, in the first part of my thesis I have discussed, synthesis of a series of novel analogs of aeruginosin 298-A, in which the Choi will be replaced with L-proline and oxygenated Choi analogs, and the …

The Women And Peace Hypothesis In The Age Of Nancy Pelosi: Can Female Leaders Bring About World Peace?, Jeannette Haynie

LSU New Orleans Theses and Dissertations

The women and peace hypothesis suggests that women are more likely than men to choose peace and compromise over violent conflict, whether as ordinary citizens or as government leaders. I test this concept by analyzing the percent of women in the parliaments and executive cabinets of 93 nations over a 31-year-period, comparing these figures to the presence of violent interstate conflicts for each country-year. Controlling for wealth, democratic status, national capabilities, military expenditures, and contiguity, I find moderate support for the women and peace hypothesis. This support continues when democratic system type is interacted with the measured office. While women …

Evolutionary Relationships Among Duiker Antelope (Bovidae: Cephalophinae), Anne Johnston

LSU New Orleans Theses and Dissertations

Duikers are a species rich subfamily of threatened African antelope whose recent origin poses a challenge to the molecular identification of taxa and estimation of their phylogeny. I test the ability of DNA barcodes to identify all taxa within this group. I then use mitochondrial and nuclear genes to estimate a multi-locus species tree and to date divergence times. DNA barcodes are unable to distinguish many sister taxa, calling into question the utility of barcodes for the regulation of duiker trade or in identification of field-collected feces. The multi-locus phylogeny provides support for the relationships among major duiker lineages and …

Snap, Nathan Feuerberg

LSU New Orleans Theses and Dissertations

The term ‘snap’ can be defined as breaking under tension as well as a sudden sharp noise. Both definitions lend themselves to the content of this short story collection and its theme of self-realization (the awakening from an illusionary self-identity or ego).

Snap is a progression of stories that revolves around waking up. Novels such as Ralph Ellison’s Invisible Man, Margaret Atwood’s Surfacing, and Paul Auster’s The New York Trilogy have all examined the issue of finding identity through a breaking of the protagonist. In each case, the protagonists come to a point where they completely separate themselves …

Factors That Contribute To Susceptibility Of The Placebo/Nocebo Effect In Experimentally Induced Ischemic Arm Pain, Steve T. Brewer

LSU New Orleans Theses and Dissertations

Placebo’s (positive expectancies producing positive outcomes) and nocebo’s (negative expectancies producing negative outcomes) are real and measurable effects. Real as these effects may be, predicting individuals that may be susceptible to placebo/nocebo effects has been inconsistent. The present study examined whether measures designed to assess somatization (MSPQ), catastrophizing (PCS) and childhood trauma (CTQ) would predict placebo and nocebo membership. In addition, measures designed to assess anxiety (ASI) anxiety about pain (PASS) and depression (BDI) were evaluated to determine whether anxiety or depression mediates responsiveness. The Hargreaves Thermal Withdrawal test and the submaximal effort tourniquet technique were employed as pain vehicles …

Bycatch Of The Lake Pontchartrain Basin Inshore Shrimp Fishery And Its Effect On Two Sea Catfish Species: The Gafftopsail Catfish (Bagre Marinus) And The Hardhead Catfish (Ariopsis Felis), Scott P. Eustis

LSU New Orleans Theses and Dissertations

In Lake Pontchartrain Basin, commercial fishing in estuarine habitats impacts many non-target species collected as bycatch. I investigated the bycatch assemblages collected by commercial vessels and compared these to assemblages collected by typical fishery-independent methods. I compared assemblages using analysis of similarity (ANOSIM) and determined important species by weight and abundance using similarity percentages analyses (SIMPER). I also examined differences in size-class distributions by gear type using density kernel plots and Mann-Whitney U tests. The two gear types collected significantly different assemblages (ANOSIM R = 0.522, p = 0.001) and gear type explained more composition differences than other factors such …

A Baseline For Downtown Transit-Oriented Development: Planning For Success In The Loyola Corridor, Peter Bennett

LSU New Orleans Theses and Dissertations

Transit-Oriented Development (TOD) in downtown areas is a distinct form of new development, creating walkable districts and 24-hour neighborhoods. A new streetcar on Loyola Avenue in the New Orleans Central Business District was planned to encourage new development in the area. By analyzing the current land uses and values, projections of future change predict over $500 million in added value. For this development to become a successful TOD, policies must encourage uses that generate ridership and increase walkability. Although the Loyola corridor has many historic attributes of a transit-oriented downtown, it currently lacks neighborhood identity. The new development associated with …

Transcendental Mirrors: Thoreau's Pond, Poe's Sea, And Melville's Ocean, Leslie Straight

LSU New Orleans Theses and Dissertations

Three seminal 19 th-century North American literary works feature bodies of water which serve both as key elements in their narrative structure and as symbolic entities within their meaning systems. The protagonists in Henry David Thoreau’s Walden, Edgar Allan Poe’s A Narrative of Arthur Gordon Pym of Nantucket, and Herman Melville’s Moby-Dick literally define themselves in terms of their relation to these bodies of water. The best way to determine the function of water in the texts is to analyze the initial relationship between water and the central character, the way that water serves as a reflection of the Self, …

Helping Behavior In A Globalized Community, Jenny M. Savely

LSU New Orleans Theses and Dissertations

This qualitative study examines the participation of post-Katrina residents in neighborhoods of New Orleans’ Upper 9 th Ward. I examine respondent self-concepts and attachment to the community to gain understanding of how individuals participate in voluntary helping behavior in their locality. Interview data, brief economic and cultural examination of the area, and my observations as a resident of the Upper 9 th Ward inform analysis. The experiences of respondents suggest that there is a tension between an individual’s need to seek selfverificationand their understanding of themselves and others within their own neighborhood. Respondents’ understanding of the impact of their own …
